ABS/PBT共混合金的增容研究
STUDY ON COMPATIBILIZATION OF ABS/PBT BLEND ALLOYS
【摘要】 研究了相容剂A和相容剂B对ABS/PBT共混合金体系的力学性能和熔体流动速率的影响,并用示差扫描量热法(DSC)对共混合金体系的相容性进行了研究。结果表明,两种相容剂均能有效地提高ABS/PBT共混合金体系的相容性,相容剂A、B的最佳用量为2%~3%。
【Abstract】 The effect of the compatibilizer A and B on the mechanical properties and melt index of ABS/PBT blend alloys was studied.The glass-transition temperature and crystallization parameter of alloys was analyzed by the differential scanning calorimetry(DSC).The results show that the crystallinity of blends is depressed and the crystallization of PBT is delayed by compatibilizers,which make the compatibility of two components in blends improved markedly.The optimum contet of two compatibilizers in blend alloys is 2%~3%.
